摘要： The present invention proposes an electronic memory device comprising a memory line including a memory domain. The memory line may contain a number of memory domains and a number of fixed domains, wherein each memory domain stores a single binary bit value. A multiferroic element may be disposed proximate to each memory domain allowing the magnetization of the memory domain to be changed using a spin torque current, and ensuring the stability of the magnetization of the domain when it is not being written. The domain boundary between the memory domain and one of its adjacent fixed domains may thereby be moved. An antiferromagnetic element may be disposed proximate to each fixed domain to ensure the stability of the magnetization of these. The value of each memory domain may be read by applying a voltage to a magnetic tunnel junction comprising the memory domain and measuring the current flowing through it.

摘要： Techniques for selectively translating resource requests from a program running on a computer system are disclosed. The resource request may be a request to access a file, library file, API, etc. The resource request may be a system call or library call. The computer program may be non-native to the computer system. Translation of resource requests may occur within the operating system or outside it. A resource request containing a reference to a first path and file name may be selectively translated by altering the resource request to contain a reference to a second path and file name. After selectively translating a request, he request is caused to be serviced. A resource request may be serviced by forwarding it to an operating system, and a result may be sent back to the program.

The optimizer file includes a runtime environment, application definition information, and a log. The log includes summaries of a plurality of events, the plurality of actions, and a time mark of occurrence for each of the plurality of actions. A runtime environment for debugging the application is then defined and the application runtime is set up using the application definition information in the optimizer file. Further, the method includes running the application and attaching an optimizer, then triggering each of the plurality of actions to occur at each time mark of occurrence associated with the each of the plurality of actions, and analyzing each of the plurality of actions and the plurality of events associated with the each of the plurality of actions, the analyzing includes comparing the events produced by running the application with the plurality of events in the optimizer file. If a fault is produced by the triggering, a debugger is invoked to analyze the fault.

摘要： A method for executing non-native binaries on a host computer architecture comprises receiving the guest executable binary into a computer readable medium. The guest executable binary is executed on the host computer architecture by translating the guest executable binary into a translated executable binary. Each instruction of the translated executed binary is then executed on the host computer architecture. Signals are responded to by placing signal information on a signal queue and deferring signal handling until a safe point is reached. A computer system implementing the method is also provided.

摘要： A method for executing non-native binaries on a host computer architecture comprises receiving a guest executable binary encoded on a computer readable medium. The guest executable binary is executable on a first computer architecture. Moreover, the guest executable binary includes a mutex lock encoded instructions for implementing a mutex lock. The guest executable binary is then executed on the host computer architecture by first translating the guest executable binary to a translated executable binary. The encoded instructions for implementing a mutex lock are translated by mapping the mutex lock to an instance of a compound mutex lock data structure. A computer system implementing methods for executing non-native binaries on a host computer architecture is also provided.
